Italian emigrants in Argentina and Brazil created imitations of Parmesan cheese, and in Russia, Russkiy Parmesan has become popular due to a trade embargo on Italian products. To protect the authenticity of Parmigiano Reggiano, the consortium of producers plans to insert microchips into the cheese rinds for real-time traceability. Parmigiano Reggiano can only be produced in specific Italian provinces, following strict rules on ingredients and maturation.
